Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fireproof wrapping, in particular to a fireproof heat-insulating cotton wrapping for a smoke exhaust air duct. Background Art
[0002] With the continuous development of modern construction technology, fire safety has become an important consideration in building design and construction. In buildings, smoke exhaust systems are important facilities for evacuating smoke and ensuring the safety of personnel during fires. Their performance and reliability are crucial. In order to improve the fire resistance and thermal insulation effect of smoke exhaust ducts, fireproof and thermal insulation cotton wrapping technology came into being.
[0003] During the installation of fireproof insulation cotton, the traditional practice is to first insert welding nails evenly on the insulation cotton board, and then use a welding gun to weld the welding nails to the air duct to ensure the stability of the insulation cotton. However, in the processing of the joint seams between the two insulation cotton boards, it is usually necessary to manually cut and paste the aluminum foil tape, which not only increases the workload but also reduces the construction efficiency. For this reason, we propose a fireproof insulation cotton package for smoke exhaust air ducts. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] See attached Figure 1-2 A fireproof and heat-insulating wool wrap for a smoke exhaust duct includes a rock wool board 1, an aluminum foil tape 2 is bonded to the upper surface of the rock wool board 1, and a film 3 is applied to one side of the aluminum foil tape 2 extending out of the rock wool board 1. The aluminum foil tape 2 is directly set on the upper surface of the rock wool board 1. When in use, the rock wool board 1 is first fixed to the duct, and then the film 3 is torn off, and the aluminum foil tape 2 can be adhered to the adjacent joint of the rock wool board 1. There is no need to cut the aluminum foil tape 2, which greatly improves work efficiency.
[0034] The width of the aluminum foil tape 2 applied to the rock wool board 1 is not less than 1 cm, which improves the tightness of the aluminum foil tape 2 applied to the rock wool board 1.
[0035] In the first embodiment, the aluminum foil tape 2 is circumferentially arranged on the upper surface of the rock wool board 1, and the circumferentially arranged aluminum foil tape 2 is connected end to end, and the end to end connection is arranged at the diagonal of the rock wool board 1, ensuring that the side walls of the rock wool board 1 at the joints and edges of adjacent rock wool boards 1 can be attached to the aluminum foil tape 2, effectively reducing the transfer of heat through the gaps, thereby improving the thermal insulation effect.
[0036] In this embodiment, two films 3 are attached to one side of the circumferentially arranged aluminum foil tape 2 with the center line as the boundary, so that the films 3 can be easily torn off from the aluminum foil tape 2 .
[0037] Since the aluminum foil tape 2 is arranged circumferentially, while it is convenient to stick the aluminum foil tape 2 on the joint seams between adjacent rock wool boards 1, a large amount of aluminum foil tape 2 will be repeatedly pasted and wasted. In order to solve the problem of repeated pasting of the aluminum foil tape 2 and waste, the fireproof insulation cotton wrapping of the smoke exhaust duct provides a second embodiment, referring to the attached Figure 3-5 The difference between the embodiment 1 and the first embodiment is that the aluminum foil tape 2 is diagonally arranged on the upper surface of the rock wool board 1, one end of the diagonally arranged aluminum foil tape 2 is arranged at the center line of the rock wool board 1, and the aluminum foil tapes 2 on adjacent rock wool boards 1 are staggered and respectively adhered to another rock wool board 1. The rock wool board 1 at the edge can reduce the waste of the aluminum foil tape 2 by cutting the aluminum foil film, and can also reduce the workload of manually cutting and bonding the aluminum foil film.
[0038] In this embodiment, the aluminum foil tape 2 is arranged diagonally and is divided into two sections, which are joined at the diagonal positions of the rock wool board 1 , so that the aluminum foil tape 2 can be stored and folded to the side of the rock wool board 1 .
[0039] See attached Figure 6-10 A fixing component for fixing the aluminum foil tape 2 to the side wall of the rock wool board 1 is provided at the diagonal portion of the rock wool board 1. The corners of the aluminum foil tape 2 are folded inward, and then the aluminum foil tape 2 is fixed to the side wall of the rock wool board 1 using the fixing component to reduce the damage rate of the aluminum foil tape 2 during transportation and ensure smooth construction.
[0040] The fixing component includes a fitting portion 41 that fits the outer wall of the aluminum foil tape 2, a pressing portion 42 that is pressed against the upper surface of the rock wool board 1 extends downward from the top of the fitting portion 41, and a positioning foot 43 extends toward the rock wool board 1 from the bottom of the fitting portion 41, and the top of the positioning foot 43 fits against the lower surface of the rock wool board 1, which greatly improves the fixing force of the fixing component on the aluminum foil tape 2 and facilitates the disassembly of the fixing component.
[0041] Furthermore, one side of the pressing portion 42 is in contact with the side of the aluminum foil tape 2 bonded to the rock wool board 1 , thereby increasing the fixing strength of the fixing component on the aluminum foil tape 2 .
[0042] Furthermore, the width of the positioning foot 43 that fits the lower surface of the rock wool board 1 is not less than 1 cm, and a protrusion is provided on the positioning foot 43 to increase the friction between the positioning foot 43 and the rock wool board 1, thereby preventing the fixing component from falling off and increasing the fixing force of the fixing component on the aluminum foil tape 2.
